Abstract

L'invention concerne un procédé de mesure de la résonance quadrupôle nucléaire d'un échantillon, dans lequel l'excitation appliquée à l'échantillon est effectuée de telle façon qu'on puisse obtenir des informations de phase et d'amplitude du signal de réponse, et dans lequel le signal est résolu en deux composantes. Notamment, si un paramètre tel que l'intensité de champ de radiofréquence varie en fonction de la position, cela peut donner une indication de la répartition de noyaux dans l'échantillon, de préférence à partir de la phase du signal de réponse. On peut également obtenir des informations de position en procédant à une mesure à partir de deux points de référence ou plus. Ce procédé peut être utilisé en imagerie. On peut utiliser les informations de phase pour améliorer le rapport signal/bruit susceptible d'être obtenu dans d'autres procédés dans lesquels seules les informations d'amplitude étaient disponibles antérieurement, par exemple en distinguant de vrais signaux de réponse à résonance quadrupôle nucléaire de signaux parasites.
